SLATE AND COAL. SEPARATlN G DEVICE.

srncrrroarron forming part of Letters Patent No. 655,161, dated. July 31, 1900. Application filed December 9, 1 99. Serial No. 739,783. (No model.)

To all whom it may concern.-

a citizen of theUnited States of America, residing'at Allegheny,- in the county of Allegheny and State of Pennsylvania,have invented certain new and useful Improvements in Slate and Coal Separating Devices, ofwhich the following is a specification,referencebeinghad therein to the accompanying drawings My invention relates to certain new and useful improvements in separators, and is particularly adapted for separating slate from eoa i One object of my invention is to construct a separator of this character with a continuous carrier which is adapted to separate coal from slate, causing the coal to travel in an opposite direction to that of the slate during the separating operation.

A further object of my invention is to pro vide means in a device of this character for elevating and lowering the continuous carrier to the desired angle.

A further object of my invention is to provide means in a device of this character for keeping a continuous carrier taut, so that the operation of the separating will not be interrupted. l

A still further object of my inventionis to providea device of this character with means for discharging the coal and slate up'on dif ferent parts of the carrier.

Briefly described, my invention consists of a rectangular frame mounted upon suitable standards having secured thereto a hopper to permit of the discharging of the coal and slate upon a continuous carrier, which is mounted upon a pair or drums suitably journaled in the said frame and provided withmeans for elevating or lowering the carrier to any angle desired and withmeansfor keeping the carrier taut.

My invention construction, combination, and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the.

claims. o

In describing the invention in' detail reference is had .to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate finally consists in the novel X icorresponding parts throughout the several Be it known that LPHILLIP F. POORBAUGH,

"-viewsgin which-' 2 Figure 1 is a longitudinal sectional view of myiirnproved separator. Fig. 2 is a rear view of the hopper, showing the adjustable slideplate for regulating the size of the dischargeopening of the said hopper. Fig. 3 is a perr spective view of the adjustable bearing to permit of the elevating and lowering of the Fig. 4 is a perspective view of a carrier. portion of the carrier. Fig. 5 is a perspective view of'a modified form of a portion of the carrier. Fig. 6is across sectional view taken on the line ww'of-Fig. 5. '.Referring to the'drawingsby reference numerals, 1 indicates a rectangular frame supporte'd'at its upper-end upon a cross-brace 2, secured to a pair of standardsfi; (only one shown, and at its"lowlei* en'd upon a crossbrace (not shown) secured toapair 'of standards i of less height than the standards 3, (only one of these standards 3 4: being shown.) The rectangular frame has each side formed with an upward extension5 at the center thereof and in which is journaleda transversely-extending friction-roller 6. The inner faces of the sides of the rectangular frame at their lower ends have suitably connected thereto a pair of vertical guide-plates 7 8, between which operates a lower sliding or adjustable bearing 9, having formed integral therewith a bushing 10.

11 indicates a guide suitably connected to each inner face of the' sides of the frame, as

ing, through which operates' the vertical adj u'sting-screw 12, having its lower end secured to the bearing 9, as shown; andjon its upper end carries a hand-wheel 14C. 6 The inner faces of the sides at their upper ends'are provided .with a pair of longitudinally-extending guideplates 15 16, between which operates the upper sliding or adjustable bearing 17. t

18 indicates a guide suitably connected to the inner face of the upper ends of the sides ofthe rectangular frame and is provided with an opening, through which operates a longitudinal adj usting screwil9, having its inner end secured to'the be'aringrl? and its outer end provided with a hand-wheel 20.

J ournaled in the bushings 10 of the lower PENNSYLVANIA, AssicNoa or ONE- shown, and is provided with a suitable openand slate upon the carrier when the same is g'agingthe bottom '31-, as shown, and having 4 are'placed on I 30 indicates bearings 9 is a transversely-extending. shaft 21, upon which is mounted a drum 22, and journaled in the upper bearing 17 is a trans- Versely-extending shaft 23, upon which 1 ecured adrum 24, and these drums 22 24 have mounted thereon a continuous carrier, to be hereinafter described. I

My continuous carrier "for separating coal and slate consists of a pair of continuous strips 25 of suitable material, which are mounted upon the drums 22 24 and which have mounted thereon a series of rectangular inclined metal plates 2 6,-secured at their upper ends, as at 27, to the strips 25, as shown, and at their lower ends overlapping each other, as at 28. The sides of these plates are bent at an angle, as at 29, forming a flange to retain the coal in position. Theupper end of each of these angle portions of the plates 26 is cut away, as shown at30, to permit of the overlapping of each adjacent plate.

V a hopper provided at its lower end with a hinged bottom 31, forming a chute, and at one side with an adjustable slide 32, which is adjusted by means of bolts 33 and nuts 34.- The bolts operate through one side of the hopper and through the slots-35, arranged in the slide, as shown. The hopper is supported above the continuous carrier by the standards 36 37, secured to the sides of the frame 1', as at 38 39. (Only one of each of these standards is shown.) The opening in the bottom of the hopper 30 is regulated by means of a screw-rod 40, operating thrpugh a suitable bushing 41, mounted upon the crossb'race 42, the inner end of the screw-rod enon its outer end a suitable hand-wheel 43.

To permit of'alongitudinal movement, if desired, of the shaft 23, a slot 44 is provided in each side'of the frame. :In the modified form of construction shown in Figs-5 and 6 of the di'awings the rectangular'overlapping'plates. instead of having their ends bent at an angle are each provided with the angle-irons 45, which are secured to the plates, as shown, and the fastening means 46 at one end of the angle-iron 45 is secured to the plate only, while the fastening means 47 at the opposite end of the angle-iron 45 is secured to the plate and flexible strip. It will also be noticed that the width of this angle-iron is not as great as the width of the plates, which permits ofthe plates overlappingin the manner as heretofore referred to. CThe operation of my improved separator is as'follows: Motionbeing imparted to the shaft 23, the drums are revolved, moving the carrier therewith, and as the coal and slate the series of metal plates form- .ingthe carrier" the coal will ride downward and be discharged over the drum at the lower endthereof, while the slate will be carried upwardly upon the carrier and be discharged therefrom at the upper end thereof. Attention is called to the fact that by means of turning the by means of the what I claim as new, and desire to Letters Patent, is-

/ frame mounted at E 8 secured to the inner faces of the frame at its lower end, bearings 9 mounted to slide verf ticallyin said guides, adj usting-screws 12 connected tosaid bearings and operating througlr guides attached to the frame,

;by the frame above the of the adjustable slide-plate 32 on oneside of the hopperand the hinged bottom 310m the opposite side the size of the opening in the bottom of thehopper may be regulated and the material also discharged at different pointsupon the carrier, as will be readily apparent, by changing the relativepositions of the bottom 3I'and slide-plate'32. Attention is also called to the manner of elevating or lowering the lower end of the carrier by means screws arranged at this part o-f the frame and elevating or lowering the .bearings 9, carrying the shaft, drum, and carrier therewith, and attention is also called to themeans for keeping the carrier taut by the longitudinal adj screw-rod, as heretofore referred to.
